(here's a fun question repeat, from more than five years ago)
Maybe we can't all have a Bolivar-signed cesta, but that doesn't mean we can't have favorites. Could it be:
a pelota with secret codes?
a Bridgeport opening night program?
a cocktail napkin autographed by Corky?
So, what's the one thing you most use to impress your guests?
